HUGE-BUCK.

To all whom it may concern:

Be it known that we, Canaries K. OLBERG, a subject of the King oi Norway, and EMERY L. WALKER, a citizen of the United States, both residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful lmprovements in Door-Bucks, of which the following is a specification.

Our invention relates to door bucks for metallic frames which are assembled and placed in position to form a door opening or other opening in a wall, the brick-work or masonry then being built around the same.

The objects of our invention are to provide improved devices of this character having provision for easily and edectively anchoring or securing the same to the wall, ceiling, etc.; our invention also relating to the means by which the upright and transverse members of the buck are secured to each other.

Our invention accordingly comprises the improved door buck referred to and a method of assembling or forming the same.

In order that our invention may be moreclearly understood, attention is hereby directed. to the accompanying drawings forming part of this application and illustrating preferred forms of our invention.

In the drawings, Figure 1 represents a front view of the assembled door buck mounted in position about a door opening, Fig. 2 represents a side elevation oi the door bucl'r,'- -the adjacent wall not being shown, Fig. 3 represents a vertical section taken on line 33 of Fig. 4, Fig. l represents an enlarged horizontal section taken on line 4. l of Fig. 1, Fig. 5 represents an enlarged side elevation of the parts shown in Figs. 3 and 4, Fig. 6 represents a vertical section taken on line 66 of Fig. 7, Fig. 7 is an enlarged section taken on line 77 of Fig. 1, Fig. 8 represents an enlarged vertical section through adjacent ends of one of the upright members and bottom transverse member of a'modified form of construction, and Fig. 9 is a side elevation of the parts shown in Fig. 8, Fig. 10 is a section on line l010 of Fig. 11, and also, to an enlarged scale, on line 10-10 of Fig. 1, showing a construction in which a pocket is formed on a flange of one of the members of the buck instead of on the web, Fig. 11 is a front view, partly broken Specification of Letters Patent.

away of the construction of Fig. 10, F lg. 12 IS a vertical sectional detail of a modified form of construction, and Fig. 13 is av side elevation of the parts shown in Fig. 12. Referring to the drawings, the door buck is formed ct upright members 1 and. 2, top transverse member 3 and bottom transverse member 4:, all of which are preferably formed of structural steel shapes, preferably cold rolled strip steel, cold drawn to a channel shape, as is shown in Fig. 4:, in which upright member 2 is represented as having a web portion 5 and flanges 6 and 7. These members may be made of various widths so as to be applicable to any desired thickness of wall or partition.

Upright members 1 and 2 are provided on their web portions with pockets 8, adapted to receive anchors by which the buck is firmly secured to the adjacent wall or par.-

tltion. Fhe pockets, as we term them, are

preferably formed by pressing the metal of a member, such as the web portion of an upright member, outwardly of the door frame, the metal at the upper and lower edge of the pressed out portion, when a pocket in an upright member is being considered, being cut through in the operation, so that a horizontally extending strap 8 on the web of the upright results, integrally secured at its ends to the metal of the web, and separated from the metal of the web at its upper and lower edges. @r the pockets may be formed in other ways, as by leaving the strap or flap referred to secured to the metal of the web at its lower edge, while cutting it through at the upper edge, thus forming a pocket open at the top and closed at the bottom; and such pockets may be formed on the transverse members as well as the upright members, and formed in the flange portions of the members instead of in the web portions, if desired, all as will be more fully set forth hereafter. Anchors 10 having portions .11 bent at right angles to the bodies of the anchors areprovided, the portions 11 of the anchors being inserted in the pockets 8 and the horizontal portions of the anchors extending into the adjacent wall or partition. As the wall l2, 13 is built up around the door buck after the latter has been assembled and raised into position, the anchors are mounted in the difierent pockets 8 of the upright members tion of an anchor which engages within its pocket is freely movable up and down in the same, when it is placed therein, the anchors are adjusted so that thefhorizontal portions thereof lie upon the tops of the adjacent layers of brick or masonry, the

next layer then bein built on top of an anchor so placed to firmly secure the buck to the wall. lhe buck may be secured to the ceiling arch by means of pockets 8 of the same construction as that just described in which are mounted anchors 10 of the same construction as the side'anchors just described, anchors 10 being fastened to the ceiling arch by means of nails or expansion bolts 14, according to the nature of the arch.

When a pocket 8 takes the preferred form of a horizontal strap, as described, the vertical portion 11 of the anchor inserted therein extends all the way through the so-called pocket and bears, below the strap of the pocket, against the surface of the web below the strap, this surface of the web being the outer side with reference to the door opening, or the inner side, with reference to the angular upright member itself, when the latter is mount-ed, as shown, with it's flanges on the outer side of the member with reference to the doorway opening. By making portions 11 of the anchors long enough to have a substantial bearing agamst the upright, the anchors will be held in position with their outwardly extending flanges horizontal, before the surrounding Wall has risen high enough to have the horizontal portions of the anchors laid thereon. If the pockets are open at the top but not at the bottom, the anchors would not be braced as well in the pockets, and their outwardly-extending flanges would tend to incline downwardly from the horizontal, before the same were secured to the wall.

The top tie member 3 is preferably secured to the uprights 1 and 2 by notching back the flanges at the opposite ends of member 3 for a suitable distance and bending the corresponding portion of the web at each end of the. transverse member 3 to a right angle to form the angular extensions 15, 15. The length of the portions 15 of member 3- is slightly less than the depth of pockets 8 in upright members 1 and 2, and the length of transverse member 3 between its angular extensions 15 is the same as the distance between the outside surfaces of the web portions of uprights 1 and 2, that is, the outside surfaces of the same with reference to the doorway opening. Accordingly, transverse member 3 may be mounted in position by simply slipping the ends of member, 3 through pockets 8 and through the slots at the lower ends of the said pockets so that the flanges 15 of the transverse-member contact the outer surfaces of the-web portions of the two uprights as is shown in Figs..6 and 7. I v v The bottom member tis secured to uprights 1 and 2 preferably in the same man nor, the bent ends 15', 15 of the web of member 45' preferably being inserted upwardly through the slots at the upper edges OflJhG pockets 8? at'the lower ends of uprights 1 and: 2, the flanges of member 4: extending downwardly "and resting on the concrete base A. If the pockets 8 extend to thebottom of uprights 1 and 2 as illustrated, it is not necessary that bent flanges 15 be of a length less than the depth of the corresponding pockets as was the case where a trans- Verse member is secured to uprights intermediate their ends as is illustrated in connection with the top transversemember 3. I

The transverse members may be secured to the uprights, if desired, by the modified construction shown in Fig. 8, in which a transverse and an upright member, such as 4 and 2 are secured together by means of a metallic angular member separate from the transverse and the upright member, this member-having a horizontal portion 16 and a vertical portion 17 This connecting piece may be secured to the end of one of the members and have its angular extension inserted through the slot ina pocket 8 for example, to hold the tie and upright members together. Thus flange 16 of a connecting piece may be welded or riveted to the web portion at one end of transverse member 4, so that its right angled extension 17 ma y be inserted through the slot at the top of a pocketB", and the same at the other. end of member 4. Qr the horizontal portion 16 of the connectmg piece might be secured to the inner side of a flange of member 4, instead of being secured to the web portion. In case such a connecting piece is used, it is not necessary that the flanges adjacent the end of the transverse member should be notched back. As stated, the pockets may be formed on the transverse members, and found useful for the reception of anchors, as well as on.

the upright members. Thus top tie member 3 may have such pockets for the reception of anchors to secure it to-the. ceiling orithe constructionoverhead, either temporarily or permanently. These pockets may be formed on a flange or on the web of member 3, -with the strap or flap of the pocket either parallel to the length of the beam or transverse to the web or the flange, the outwardly extending branch of-the anchor used therewith being either vertical or horizontal, as desired. A construction is illustrated in Figs. 10 and 11 in which the pocket is formed on a flange of member 3. Also, the pockets on the uprights may extend horizontally, if desired, instead of vertically, so that the outer portions' of the anchors would extend between vertical courses of the wall instead of between horizontal courses. And similarly, the pockets on the uprights may be formed in the flanges instead of in the webs of the same, in which case they preferably extend parallel to theflange, that is, with vertical openings instead of horizontal. whilethe construction of pocket described constitutes the preferred form of our invention, other forms ofpocket areincluded in the scope of the invention. Thus separate straps may be welded or otherwise secured to the outer sides of the members, in reference to the door-way opening, to constitute pockets for the reception of the anchors, and similar straps may be secured to the other or inner sides of the upright members to receive the bent ends of the transverse mem bers, the length of a transverse member in this case, between its bent ends, being equal to the distance between the inner sides of the uprights. Or as a somewhat different construction, which may be included within our invention, pockets for the reception of the ends llqof anchors maybe formed as indi cated in Figs. 12 and 13, in which one or more (preferably two) prongs or strips of metal 18' may be caused to extend upwardly, in the case of an upright member,-from a connection indicated'atlQ with the metal of theweb olf the upright. These pieces 18 may be welded or otherwise secured to the outer side of the web, inreference. to the doorway opening, or preferably are formed, as shown in the drawings, by cutting through the II. etal of the upright to form an opening or openings, preferably rectangular, the cut out portionor portions, namely the piece or pieces 18, beinglleft integral with the'web attheir lower edges,'to extend upwardly and form a projection or' p'rojections over which the end of an anchor may be positioned, as shown. The same construction may be 'us'edfor securing a transverse member to an upright, by causing the prong or .prongslB to extend; upwardly on the inner, instead of the outer, side of the upright, and providing the transverse member with a dow'nwardlybent web end to hook over the same.

f It should be understood that whenever, in the claims, we referto a pocket}? the term is intended to broadly include the various forms of construction described, when the same constitutes a strap portion, having openings on opposite sides thereof, as well as when the same has an opening at one end thereof only, and that whenever, in the claims, a pocket is stated to be open at one end thereof, the language used is not intended to exclude openings on both opposite Further,

ends thereof. And it should be understood that our invention is not limited to the forms of construction described, but is broad enough to include reasonable equivalents, in accordance with the claims appended hereto.

From the above description, it may readily be understood that the entire door buck may be assembledon the floor and then raised up and placed in position whereupon concrete or the like may be grouted in at the bottom, the buck anchored at the top as described, and the partition or wall then built up around the entire buck, the various anchors being secured in position during the building of the wall.

In the drawings, the reference character A represents the base on which the buck is erected, and the surface B represents the finished floor, which may be of concrete or the like, as stated.

it will be seen that by the means described, a rigid and simplified construction is provided, and one that permits the ready assembling of the buck before the same is erected, and the simple and convenient anchoring of the same to the surrounding wall, when erected, and as the wall is placed in position.

Having described our invention, what we claim as new therein and desire to secure by Letters Patent of the United States is 1. A door buck comprising upright members and transverse members formed of channel shape having their flanges outwardly directed, said upright members having pockets formed on the outer sides of their web portions, with reference to the interior of the completed buck, by pressing a portion of the metal outwardly and forming a slot at one end of the pressed out portion of each pocket, anchors inserted in some of said pockets and having portions adapted to extend into the adjacent brick work or masonry, and said transverse members being secured to said upright members by angular metallic members extending through some of said slots and securing together. the adjacent ends of the web portions of the transverse and upright members, substantially as set forth.

2. A door buck comprisin upright members and a transverse mem er formed of channel shape, with their flanges outwardly directed, said upright members having pockets formed on the outer sides of their web portions, with reference to the interior of the completed buck, by pressing the metal in each outwardly, to form straps having openings through the metal above and below the straps, and said transverse member having its flanges notched back at its ends, and its web. portion at its ends bent at right angles, said transverse member being of a. length between its bent ends equal to the distance between the outside faces of the webs of said upright members, and safi transverse member being mounted in pos 1 tion with its bent ends inserted through said inseam This specification signed and witnessed this 24th day of 511116,.1914.
